1.DN3600mm the largest diameter single sphere rubber joint introduction: 

1)This product can greatly reduce pipeline system shock and noise. And can

 fundamentally resolve pipe joints displacement, axial stretch and non-concentricity.

  

2)By using different materials, it can be made many kinds to cater for different medium 

and environment. Such asacid resistance, alkali resistance, corrosion resistance, oil resistance and heat resistance etc.

 

3)The material is purerubber, sealing is very good. It is in light weight, very easy for 

installation .This product has long life performance, but must be not contact with sharp metal instruments to avoid piercing the sphere. 

 

4)The product can be used for lift and transportation of raw water and sewage,transportation

of water supply cooling cycle water thermal power ,condensate water of metallurgy industry and chemical industry.

 

2.Material list:

NO	NAME	MATERIAL
1	Inner rubber	ⅡR,CR,EPDM,NR,NBR
2	Outer rubber	ⅡR,CR,EPDM,NR,NBR
3	Framework layer	Polyester cord fabric
4	Flange	Q235
5	Reinforcing ring	Steel wire rope

 

Note:

 

1. The size up to 3600mm (144").

 

2. The flange standard could be ANSI, GB, DIN, BS, or some other standard as per custom request.

 

3. The pressure is 6Mpa, 10Mpa, 16Mpa, 25Mpa.

 

 

3. Production progress

 

 

1. Raw material: we never use reclaimed raw rubber, rubber is imported from USA. Before used, raw material should be tested, including physical test and some chemical experiment to test the hardness and so on;

2. Rubber pretreating and ingredients;

 

3. Milling: first, rubber plastication, second, rubber mixing, we will add rubber compounds, like sulfurzing reagent, surfactant, softener, stabilizer, foaming agent and some special compounds, at the same time, rubber will be extruded into plates, cut, produce 45 degree angle. The plates cannot directly be used, they should be cooled about 24 hours;
